Apply Gaussian:
 
Reference version:

FWHM = ΔM
(Peak Full Width at Half-Maximum)

Resolution = M / ΔM

If you want to provide from your website a link from a molecular formula in order to calculate:

  • Molecular weight and monoisotopic mass
  • Element analysis
  • Isotopic distribution

You may directy add a code like:

<a href="http://www.chemcalc.org/service/analyse?mf=PhSiMe3" target="_blank">
PhSiMe3
</a>

Don't forget to escape the molecular formula if you have non standard characters like "+" (charged molecular formula).

If you want to generate a link for "HAla100OH++" You should use as link:
